Since ArcGIS.com is a place for building Web Maps and storing other mobile content, shouldn't there be a mobile version of the site for smaller devices. Many sites on the web have a mobile version that replaces the full version of the website when it's accessed by a mobile device like a smart phone. These mobile sites are much easier to navigate, load less content and provide a better browsing experience for mobile devices.
For example, creating a Web Map for consumption on ArcGIS for iOS can be done with ArcGIS.com. If the iPhone is the only available option for finding content, building a web map and sharing it, having a mobile version of ArcGIS.com would really make the process much easier.
